To aZZ whom it may concern.-

Be it known that 1, WILLIAM T. CARROLL, of WVoreester city and county, State of Massachusetts, have invented an Improvement in Spindle-Supports for Spinning-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention in spinning-machines has for its object to improve the support for the spin dles, whereby the latter may be run steadily without the employment of bolsters surrounded by elastic or other packings, such as are now commonly used.

My invention consists, essentially, in the combination, with the spindle, of a yielding upright spindle supporting standard provided at its upper end with a longitudinallyarranged chamber for the reception of the foot of the spindle, the sleeve-whirl surrounding the upper end of the said standard, substantially as will be hereinafter described, and as represented in the drawing hereunto annexed.

The drawing represents in side elevation a sleeve-whirl spindle and spindle-supporting standard, both broken out at their junction to show the pintle of the spindle entered into the opening at the top of the standard, the usual rail being shown in section, while the securing'nut below it is in elevation.

The rail A, of usual construction, has at tached to it by nut A the spindle'supporting standard B, the upper end of which, extended above the line of the band-pull, is provided with a chamber, in which is placed the pintle of the sleeve-whirl spindle O, the said chamher also receiving oil. The sleeve-whirl surrounds the upper end of the standard, as shown in the drawing, and the bottom of the usual band-groove and the whirl is located at considerable distance below the top of the standard.

In ring-spinning frames it is well known that the bearings for the rapidlyrevolving spindles have to be supported in such manner as to permit the loaded spindles to move some what in any direction laterally, to thus enable the unevenly-loaded or improperly-balanced spindles to find their true center of rotation, and thus obviate injurious strain or jar of the parts and the production of bad or imperfect yarn.

In my experiments I have ascertained that by the employment of a long standard, such as showna standard nearly or quite as long as the spindlethe necessary amount of elasticity may be readily gained without the employment of elastic packing or an oil or fluid packing such as heretofore used in rapidlyrotating spindles.

The spindle O and its attached sleeve-whirl are of usual construction. The standard B in practice is sufficiently rigid to obviate its being bent or deflected by strain due only to band-pull; but the standard is sufficiently flexible to permit its upper end to yield to a limited extent to accommodate for those strains in spinning due to rapid rotation of the spindle with an unbalanced load. The flexible or yielding standard also acts to keep the band taut under usual climatic changes. The standard is provided with a collar, (2, attached thereto by a set-screw, e, the said collar serving to sustain the hook f, of usual shape, employed to cooperate with the sleeve-whirl to prevent the withdrawal of the spindle from the standard when dotting the bobbins from the spindles in usual manner.

The bearing for the lower end of the spindle is so far elevated above the flange B or pro jection of the standard, which flange bears on the top of the rail A, as to afford between the said bearing and the flange or projection a portion of considerable length which can yield to the requirements of the spindle.

I claim- 1. The rail and the spindle'supporting stand ard B, erected above it and provided with a flange or projection, B, to rest upon the said rail, and bored at its upper end for the reception of the pintle of the spindle, leaving a yielding portion of the said support between the flange or projection and the lower end of the spindle, combined with a sleeve-whirl spindle having a pintle extended below the sleevewhirl, the sleeve of the whirl extending down about the upper end of the said standard, substantially as described.

2. The rail and thespindle-supporting stand ard B, provided with a flange or projection, 13, to rest on the rail, and bored at its upper end for the reception of the lower end of the spindle, leaving a yielding portion of the said support between the flange or projection and the lower end of the spindle, combined with a sleeve-whirl spindle, the sleeve of the whirl extending down about the upper end of the said standard, and with a hook, f, and means to connect it with the spindle, substantially as described.

WILLIAM T. CARROLL.
